Description

Technical Field

[0001] This invention relates to the field of glue needle cutting technology, specifically the VLoop automatic glue needle cutting machine. Background Technology

[0002] VLoop glue needles are glue needles with a special "V"-shaped bending design, suitable for VTOOL ferrule guns, and are mainly used for hang tags on clothing and textile products. While ensuring a secure connection, they effectively address the industry pain points of clothing fabrics being puncture-resistant and soft, making them difficult to grip for hang tag installation. This makes them a common choice for companies that value packaging details and brand image (especially clothing brands).

[0003] In the existing technology, most VLoop needle cutting equipment on the market adopts a single-cutter structure design. The cutter is usually directly fixed on the drive component, without a dedicated cutter fixing seat and support column connection structure, and it does not adopt a symmetrical distribution layout. For material structures that produce multiple VLoop needles per mold, such equipment can only cut off the bridging material shank between one VLoop needle and the material shank in a single cut, and complete the entire cutting operation of one mold of material, requiring multiple repetitions of positioning and cutting actions. However, on the one hand, the asymmetrical layout of the single cutter combined with the direct fixing method results in poor synchronization between the movement of the cutter and the drive components during the cutting process, which easily leads to problems such as cutter deviation and vibration. This not only affects the flatness of the cut, but may also damage the finished glue needle due to positioning deviation. On the other hand, only one glue needle can be cut at a time. For material structures with multiple pieces per mold, the equipment needs to be started and stopped multiple times to complete the cutting. Each cutting requires repositioning the material, which not only significantly extends the processing cycle of a single mold material and slows down the production cycle, but also the frequent positioning and start-stop actions can easily aggravate the wear of equipment components and reduce the service life of the equipment. It cannot meet the needs of high-efficiency production of large batches of VLoop glue needles, resulting in low production efficiency.

[0004] Therefore, we have launched the VLoop automatic glue needle cutting machine. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic VLoop glue needle cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic VLoop glue needle cutting machine, comprising: an electrical control cabinet, an upper mold column, and a VLoop sprue stalk;

[0007] The top of the electrical control cabinet is provided with a square box panel, and multiple sets of lower mold support columns are provided at the center of the top of the square box panel. The top of the multiple sets of lower mold support columns is provided with a lower mold support plate.

[0008] The upper mold columns are evenly spaced on the top of the square box panel and located outside the lower mold support columns. The top of the upper mold columns is provided with an upper mold support beam, and the top of the upper mold support beam is fixedly provided with an upper mold fixing plate.

[0009] The VLoop sprue handle is located on the top of the lower mold support plate. VLoop bridging handles are provided on both sides of the VLoop sprue handle, and VLoop glue needles are provided on one side of the VLoop bridging handle.

[0010] Cylinder A is provided on both sides of the top of the upper mold fixing plate. The output end of cylinder A is connected to a pre-pressure plate. A fixing component is provided at the bottom of the pre-pressure plate. Through the cooperation of the pre-tightening plate guide post, the upper mold pressure strip guide sleeve and the upper mold pressure strip of the fixing component, the upper mold pressure strip fixes the VLoop glue needle on the top of the lower mold support plate.

[0011] Preferably, the pre-tightening plate guide posts are connected at equal intervals to the four bottom corners of the pre-pressing plate, the upper mold pressure strip guide sleeve is slidably connected to the surface of the pre-tightening plate guide posts, and the upper mold pressure strip is connected to the bottom of the upper mold pressure strip guide sleeve. The upper mold pressure strip is located above the VLoop glue needle and the lower mold support plate.

[0012] The bottom of the upper mold fixing plate is equipped with a cutting mechanism. Through the cooperation of the push plate, the cutter fixing seat and the cutter of the cutting mechanism, the cutter cuts off the VLoop bridging material stalk between the VLoop sprue stalk and the VLoop glue needle.

[0013] Preferably, the cutting mechanism includes a cylinder B positioned at the center of the top of the upper mold fixing plate. The output end of cylinder B passes through the pre-pressing plate and connects to the push plate. The bottom of the push plate is connected to multiple sets of cutter fixing support columns, and the cutter fixing seats are connected to the bottom of the multiple sets of cutter fixing support columns. The sides of the cutter are bolted to both sides of the cutter fixing seats, and the cutter fixing seats and the cutter slide against the inner sides of the two sets of upper mold pressing strips. The centrally positioned cylinder B can provide a uniform and stable driving force. The through-type connection design ensures efficient power transmission. The bolted cutter facilitates subsequent replacement and maintenance, while the sliding layout avoids interference with the pressing structure during the cutting process.

[0014] Preferably, push plate guide posts are connected to the top four corners of the push plate, and the bottom of the upper mold fixing plate is provided with an upper mold fixing plate guide sleeve above the push plate guide posts, and the push plate guide posts are connected inside the upper mold fixing plate guide sleeve; the four corner guide posts and guide sleeves provide precise guidance for the lifting and lowering movement of the push plate, effectively preventing the push plate from deviating or tilting during the movement, and further ensuring that the cutting trajectory of the cutter is accurate and controllable.

[0015] Preferably, the top of the pre-pressing plate is provided with a cylinder support column at the bottom of the output end of cylinder A, and the pre-tightening plate guide column passes through the push plate; the cylinder support column can increase the contact area between the output end of cylinder A and the pre-pressing plate, so that the pre-pressing plate is subjected to force more evenly and avoids local deformation, while the design of the pre-tightening plate guide column passing through the push plate can achieve dual guidance and improve the motion stability of the entire pressing mechanism.

[0016] Preferably, the bottom of the VLoop glue needle is provided with a VLoop material belt; the VLoop material belt can play an auxiliary role in supporting and leveling multiple sets of VLoop glue needles, ensuring that the glue needles maintain a uniform posture during the cutting process, while facilitating the overall loading and subsequent handling of materials, further improving the convenience of operation.

[0017] Preferably, a cylinder C is connected to the lower die support plate, and the piston rod of the cylinder C is connected to the lower die pressure strip. The lower die pressure strip slides on the lower die support plate and moves horizontally. The lower die pressure strip is used to press the VLoop material strip. The cylinder C drives the lower die pressure strip to move horizontally, which can reliably press the edge of the VLoop material strip. It forms an upper and lower coordinated pressing structure with the upper die pressure strip, which prevents the material from shifting during the cutting process in all directions and ensures the cutting accuracy.

[0018] Preferably, an emergency stop switch is provided on one side of the top of the electrical control cabinet, and a start button is provided on the surface of the electrical control cabinet on the side of the emergency stop switch. The emergency stop switch can quickly cut off the power supply and pneumatic circuit of the equipment in case of sudden failure or emergency, so as to ensure the personal safety of the operator and the safety of the equipment. The start button is used to conveniently trigger the automatic operation process of the equipment. The two are reasonably arranged and facilitate quick operation by the operator.

[0019] Preferably, the electrical control cabinet has a square box body at the bottom, and omnidirectional casters are connected to the four corners of the bottom of the square box body. The square box body can provide stable support for the electrical control cabinet, and at the same time can store auxiliary components such as air pipes and cables to keep the overall equipment tidy. The omnidirectional casters at the bottom facilitate the flexible movement of the equipment according to the production layout, improving the flexibility of equipment use.

[0020] Preferably, a baffle is installed above the lower die pressing strip to receive the cut VLoop glue needles and VLoop material strips; the baffle adopts an inclined design, which allows the finished glue needles after cutting to slide smoothly into the collection device under their own gravity, realizing automatic separation and collection of finished products, reducing manual sorting processes, and further improving work efficiency.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) The cutter adopts a symmetrical distribution design on the left and right sides and is fixed to the cutter fixing seat with bolts. The cutter fixing seat is rigidly connected to the push plate through the cutter fixing seat support column, ensuring that the cutter and the push plate move synchronously during the cutting process. Each cut can cut the bridging material handle of two VLoop glue needles at the same time (corresponding to the material structure of producing 4 VLoop glue needles per mold. Two pieces are separated in one cut, and one mold of material processing can be completed in two cuts). The cutting efficiency of this equipment is improved, the production cycle is greatly improved, and it is suitable for large-volume VLoop glue needle production scenarios.

[0023] (2) The equipment adopts a triple positioning structure of “lower mold support plate limiting + lower mold pressure bar bottom pressing + upper mold pressure bar top pressing”. The VLoop glue needle is positioned at the reference through the lower mold support plate. The lower mold pressure bar is driven by cylinder C to horizontally press the material strip. The upper mold pressure bar is driven by cylinder A to vertically press the glue needle. With the sliding guide of the pre-tightening plate guide post and the upper mold pressure bar guide sleeve, and the sliding guide of the push plate guide post and the upper mold fixing plate guide sleeve, the movement of each positioning component is accurate and the repeatability is high. This effectively avoids problems such as material displacement during the cutting process, such as cut damage and uneven cut. At the same time, the positioning process does not require manual adjustment and fixing. The material only needs to be laid flat on the lower mold support plate and the equipment can be started to complete the automatic pressing and positioning. The clamping operation is simple and the skill requirements of the operator are low. This solves the industry pain points of cumbersome manual positioning and the accuracy depending on the operator's experience.

[0024] (3) All moving parts of the equipment adopt the guide post and guide sleeve matching structure, including the push plate guide post + upper mold fixed plate guide sleeve between the push plate and the upper mold fixed plate, the pre-tightening plate guide post + upper mold pressure strip guide sleeve between the pre-pressing plate and the upper mold pressure strip, and the sliding matching structure between the lower mold pressure strip and the lower mold support plate. The guide post and guide sleeve matching can effectively ensure the accuracy of the reciprocating motion trajectory of each moving part, avoid the problems of part wear and reduced cutting accuracy caused by motion deviation, reduce friction loss between parts, extend the overall service life of the equipment, and reduce equipment maintenance costs.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-4 The present invention provides a technical solution: VLoop glue needle automatic cutting machine, including: electrical control cabinet 13, the top of the electrical control cabinet 13 is provided with a square box panel 8, the top of the square box panel 8 is provided with multiple sets of lower mold support columns 7, and the top of the multiple sets of lower mold support columns 7 is provided with a lower mold support plate 31.

[0032] The upper mold column 9 is evenly spaced on the top of the square box panel 8 and located outside the lower mold support column 7. The upper mold support beam 10 is provided on the top of the upper mold column 9, and the upper mold fixing plate 20 is fixedly provided on the top of the upper mold support beam 10.

[0033] VLoop sprue handle 4 is an integrated connecting component for VLoop glue needle material. It is horizontally placed in the top positioning area of ​​the lower mold support plate 31 and is precisely positioned by the positioning groove on the surface of the lower mold support plate 31. Multiple sets of VLoop bridging handles 3 are symmetrically arranged on both sides of the VLoop sprue handle 4. The VLoop bridging handle 3 is a slender strip structure and is the key part connecting the VLoop sprue handle 4 and the VLoop glue needle 1. It will be cut off by a cutting mechanism later. The VLoop glue needle 1 is integrally formed on one side of the VLoop bridging handle 3. The VLoop glue needle 1 is the final finished part. Multiple sets of glue needles are integrated together by the bridging handle and the sprue handle, which facilitates batch cutting operations.

[0034] Cylinders A22 are respectively provided on the top two sides of the upper mold fixing plate 20. The output end of the cylinder A22 is connected to the pre-pressure plate 19. The bottom of the pre-pressure plate 19 is provided with a fixing component. Through the cooperation of the pre-tightening plate guide post 25, the upper mold pressure strip guide sleeve 29 and the upper mold pressure strip 16 of the fixing component, the upper mold pressure strip 16 fixes the VLoop glue needle 1 on the top of the lower mold support plate 31.

[0035] The pre-tightening plate guide post 25 is a high-strength cylindrical guide post, which is vertically connected at equal intervals to the four bottom corners of the pre-pressure plate 19. The bottom of the guide post passes through the push plate 18 and is reserved for a guide stroke. The upper mold pressure strip guide sleeve 29 is a hollow cylindrical structure with its inner wall precision machined. It is slidably connected to the surface of the pre-tightening plate guide post 25 and can slide smoothly along the guide post. The upper mold pressure strip 16 is fixedly connected to the bottom of the upper mold pressure strip guide sleeve 29 by bolts. The upper mold pressure strip 16 is a long strip structure, the length of which matches the arrangement width of the VLoop glue needles 1. The upper mold pressure strip 16 is located above the VLoop glue needles 1 and the lower mold support plate 31, and can be precisely pressed into the top area of ​​the glue needles.

[0036] The bottom of the upper mold fixing plate 20 is provided with a cutting mechanism. Through the cooperation of the push plate 18, the cutter fixing seat 28 and the cutter 17 of the cutting mechanism, the cutter 17 cuts off the VLoop bridging material handle 3 between the VLoop sprue handle 4 and the VLoop glue needle 1.

[0037] The cutting mechanism specifically includes a cylinder B21 positioned at the center of the top of the upper mold fixing plate 20. Cylinder B21 is a high-thrust double-acting cylinder, its body fixed to the surface of the upper mold fixing plate 20. Its output end (piston rod) faces downwards and passes through a clearance hole on the preload plate 19, then is fixedly connected to the push plate 18 by bolts. The push plate 18 is a horizontal flat plate structure that can move up and down along a guide structure under the drive of cylinder B21. Multiple sets of cutter fixing support columns 27 are evenly connected to the bottom of the push plate 18. Each cutter fixing support column 27 is a vertically arranged cylindrical structure used to connect the push plate 18. 8 transmits driving force to the cutter fixing seat 28; and the cutter fixing seat 28 is fixedly connected to the bottom of the multiple sets of cutter fixing seat support columns 27 by bolts. The cutter fixing seat 28 is a frame structure with cutter mounting slots reserved on both sides; the cutter 17 is a high-strength alloy cutter, and its side is detachably connected to the mounting slots on both sides of the cutter fixing seat 28 by bolts, which facilitates the replacement and maintenance of the cutter in the future; and the cutter fixing seat 28 and the cutter 17 are slidably connected to the inner side of the two sets of upper molding strips 16, and can smoothly descend along the inner guide structure of the upper molding strips 16 to avoid deviation during the cutting process.

[0038] The push plate 18 is vertically connected to four corners at the top, and the push plate guide post 26 is a precision guide post with a surface hardened and ground to ensure high guiding accuracy. The bottom of the upper mold fixing plate 20 is provided with an upper mold fixing plate guide sleeve 23 directly above the push plate guide post 26. The upper mold fixing plate guide sleeve 23 is a precision guide sleeve that matches the push plate guide post 26. The inner wall is provided with a lubrication groove, and the push plate guide post 26 is slidably connected in the upper mold fixing plate guide sleeve 23. Through the cooperation of the guide post and the guide sleeve, the trajectory of the push plate 18 moving up and down can be ensured to be accurate, thus improving the cutting accuracy.

[0039] The top of the preload plate 19 is provided with a cylinder support column 24 at the bottom of the output end of the cylinder A22. The cylinder support column 24 is a cylindrical structure. Its top is fixedly connected to the output end of the cylinder A22, and its bottom is rigidly connected to the preload plate 19. It is used to increase the contact area of ​​the force exerted by the cylinder A22 on the preload plate 19, so as to ensure that the preload plate 19 is subjected to uniform force and avoid local deformation. The pretension plate guide column 25 passes through the guide hole reserved on the push plate 18. The inner wall of the guide hole is precision machined and slides with the pretension plate guide column 25. It can play an auxiliary guiding role in the movement of the pretension plate guide column 25, and further improve the movement stability of the fixing assembly.

[0040] The bottom of the VLoop glue needle 1 is fitted with a VLoop material strip 2, which is a sheet-like structure used to carry multiple sets of VLoop glue needles 1, so that the glue needles remain flat during the cutting process, and at the same time facilitate the subsequent material conveying and sorting.

[0041] A cylinder C14 is fixedly connected to the lower mold support plate 31 via a bracket. The cylinder C14 is a horizontally arranged double-acting cylinder, and its output end (piston rod) faces the material placement area and is fixedly connected to the lower mold pressure strip 15 via a connector. The lower mold pressure strip 15 is slidably connected to the lower mold support plate 31 through the cooperation of a slider and a slide rail, and can reciprocate in the horizontal direction under the drive of the cylinder C14. The lower mold pressure strip 15 is a long strip structure, and its length matches the width of the VLoop material strip 2. It is used to press the edge area of ​​the VLoop material strip 2 to prevent the material strip from shifting during the cutting process and to ensure cutting accuracy.

[0042] An emergency stop switch 11 is provided on one side of the top of the electrical control cabinet 13. The emergency stop switch 11 is a red mushroom-shaped button. When pressed, it can immediately cut off the main power supply and pneumatic circuit of the equipment, so that all parts of the equipment stop operating. It is used to deal with sudden failures or emergencies and ensure the safety of operators. On the surface of the electrical control cabinet 13, next to the emergency stop switch 11, there is a start button 12. The start button 12 is a green button, which is used to trigger the automatic operation process of the equipment. When pressed, the equipment will complete the positioning, clamping, cutting, and resetting actions in sequence according to the preset program.

[0043] The bottom of the electrical control cabinet 13 is fixedly connected to a square box body 6 by bolts. The square box body 6 is a box-type structure, which can be used to place auxiliary components such as air pipes and cables, and at the same time provide stable bottom support for the equipment. Furthermore, the four corners of the bottom of the square box body 6 are respectively connected to swivel casters 5 by bolts. The swivel casters 5 are equipped with brake devices, which not only facilitates the flexible movement of the equipment, but also fixes the position by braking when the equipment is working, ensuring the stable operation of the equipment.

[0044] Above the lower die pressing strip 15 is a baffle 30 for receiving the cut VLoop glue needle 1 and VLoop material strip 2. The baffle 30 is an inclined plate structure with an optimized inclination angle, which allows the cut VLoop glue needle 1 to slide smoothly down the baffle surface into the collection device under its own gravity. At the same time, it can provide auxiliary support for the VLoop material strip 2 to prevent the material strip from sagging and deforming during the cutting process.

[0045] This VLoop glue needle automatic cutting machine is based on an automated process design of "positioning-clamping-cutting-resetting-material handling". Through the precise cooperation of mechanical structure and pneumatic components, it achieves efficient and precise separation of VLoop glue needles and sprue handles, eliminating the need for manual cutting throughout the entire process. The specific workflow is as follows, with reference to the connection relationships of each component and the attached diagram. Figures 1-4 Detailed explanation:

[0046] After the equipment is powered on, electrical control cabinet 13 (integrated control module) Figure 1 The system self-test is completed (located on one side above the main body 6 of the square box), and all pneumatic components (cylinder A22, cylinder B21, cylinder C14) are in the initial reset state: cylinder A22 (located on both sides of the top of the upper mold fixing plate 20, Figure 2 As can be seen, the piston rod retracts, causing the pre-pressing plate 19 to rise. The pre-tightening plate guide post 25 (through the push plate 18) connected to the bottom of the pre-pressing plate 19 rises synchronously, thereby causing the upper mold pressure strip 16 (which slides with the pre-tightening plate guide post 25 through the upper mold pressure strip guide sleeve 29) to be in a high position, away from the lower mold support plate 31. The piston rod of cylinder B21 (located at the top center of the upper mold fixing plate 20) retracts, causing the push plate 18 to rise. The push plate 18 rises smoothly to the initial position through the sliding fit structure between the push plate guide post 26 (at the top four corners) and the upper mold fixing plate guide sleeve 23 (at the corresponding position at the bottom of the upper mold fixing plate 20). The cutter fixing seat 28 (rigidly connected to the push plate 18 through the cutter fixing seat support post 27) and the cutters 17 fixed on both sides rise synchronously, located in a high position inside the upper mold pressure strip 16. The piston rod of cylinder C14 (fixed on the lower mold support plate 31) retracts, causing the lower mold pressure strip 15 to be horizontally reset along the lower mold support plate 31, away from the material placement area.

[0047] The operator places a sheet of VLoop glue needle material (material structure: VLoop glue needle 1 is connected to VLoop sprue sprue sprue sprue 4 through VLoop bridging sprue 3, and the bottom of VLoop glue needle 1 is attached to VLoop strip 2, forming a sheet-like integrated structure) onto the lower mold support plate 31 (supported and fixed at the top center of the square box panel 8 by multiple sets of lower mold support columns 7, the square box panel 8 covers the surface of the square box body 6, and the four corners of the bottom of the square box body 6 are equipped with universal casters 5 for easy equipment movement), so that the VLoop sprue sprue sprue sprue 4 is attached to the positioning surface of the lower mold support plate 31, and part of the VLoop glue needle 1 is laid flat on the baffle 30 (installed above the lower mold pressure strip 15), ensuring that the VLoop bridging sprue sprue 3 is in the cutting area directly below the cutter 17, thus completing the material loading and positioning;

[0048] After confirming that the materials are placed correctly, the operator presses the start button 12 on the surface of the electrical control cabinet 13. Figure 1 On one side of the emergency stop switch 11 (which is used to cut off equipment operation in an emergency), the equipment enters the automatic operation process: First, cylinder C14 receives a control signal, the piston rod extends, and pushes the lower die pressing strip 15 to move horizontally along the lower die support plate 31 until the lower die pressing strip 15 presses the VLoop material strip 2, thereby fixing the bottom of the material horizontally and preventing the material strip from shifting during the cutting process; then, cylinder A22 starts, the piston rod extends, and pushes the pre-pressing plate 19 downward through the cylinder support column 24 (the top of the pre-pressing plate 19 corresponds to the output end of cylinder A22). The pre-pressing plate 19 drives the pre-tightening plate guide columns 25 at the four corners of the bottom to move downward synchronously (the pre-tightening plate guide column 26 passes through the push plate 18 and is slidably positioned through the holes on the push plate 18 to ensure smooth movement). The upper die pressing strip 16 follows the pre-tightening plate guide column 25 downward through the upper die pressing strip guide sleeve 29 (which slides with the pre-tightening plate guide column 25) until the upper die pressing strip 16 presses the top area of ​​the VLoop glue needle 1;

[0049] At this time, the VLoop glue needle 1 achieves precise fixation through the triple positioning structure of "limiting by the lower mold support plate 31, pressing the bottom of the lower mold pressure strip 15, and pressing the top of the upper mold pressure strip 16". The high repeatability of the positioning ensures that the VLoop bridging material handle 3 is always on the cutting trajectory of the cutter 17, laying the foundation for subsequent precise cutting. During the entire positioning process, all moving parts cooperate with guide pillars and guide sleeves (pre-tightening plate guide pillar 25 and upper mold pressure strip guide sleeve 29, push plate guide pillar 26 and upper mold fixing plate guide sleeve 23) to ensure accurate movement trajectory and avoid positioning deviation.

[0050] After the material is clamped and positioned, cylinder B21 receives a delayed control signal (to ensure that the cutting is started only after the positioning action is completed, avoiding interference). The piston rod extends and pushes the push plate 18 to move smoothly downward along the sliding fit structure between the push plate guide post 26 and the upper mold fixing plate guide sleeve 23. During the downward movement of the push plate 18, the cutter fixing seat 28 is driven to move downward synchronously through the cutter fixing seat support post 27. The cutter 17 is fixed on both sides of the cutter fixing seat 28 by bolts. Figure 2 The cutter 17, located inside the upper mold pressure strip 16, moves downwards. Since the cutter 17 is distributed left and right (corresponding to the bridging handle position of the two VLoop needles 1), and the cutter fixing seat 28 slides with the cutter 17 inside the two sets of upper mold pressure strips 16, it will not interfere with the upper mold pressure strip 16 during the downward movement until the cutter 17 contacts and cuts the VLoop bridging handle 3, thus achieving complete separation of the VLoop needle 1 and the VLoop sprue handle 4. After the cutting is completed, the VLoop needle 1 loses its bridging handle connection function and slides off the baffle 30 under its own gravity (the baffle 30 is an inclined receiving structure, which facilitates the collection of material sliding down), thus completing the automatic separation of the cut product without the need for manual peeling.

[0051] After the cutting action is completed, cylinder B21 first receives a reset signal, the piston rod retracts, and drives the push plate 18, the cutter fixing seat 28 and the cutter 17 to rise smoothly along the guide post and guide sleeve structure, resetting to the initial high position; then, cylinders A22 and C14 start resetting synchronously, the piston rod of cylinder A22 retracts, and drives the pre-pressure plate 19, the pre-tightening plate guide post 25 and the upper mold pressure strip 16 to rise and reset, releasing the top clamping of the remaining material; the piston rod of cylinder C14 retracts, and drives the lower mold pressure strip 15 to reset horizontally, releasing the bottom clamping of the VLoop material strip 2 and the VLoop sprue handle 4. The operator manually removes the remaining VLoop sprue handle 4 and the waste material strip, completing the end work of the entire operation cycle. Then, new sheet material can be placed, and the start button 12 is pressed to enter the next working cycle, realizing continuous cutting operation.

[0052] In this embodiment, cylinder A22 is model SDA25-30, cylinder B21 is model SDA63-40, and cylinder C14 is model SDA12-10.
